As revealed by NBC only moments ago, former 'SNL' head writer and castmate Fey will return to Studio 6H to host on September 28 with musical guest Arcade Fire. The subsequent week will see Miley Cyrus taking up double duty as host and performer on October 5, while Bruce Willis will host on October 12 accompanied by Katy Perry. Presumably, Lady Gaga's hosting stint will arrive in the weeks before the November 11 release of album "ARTPOP."
